Abstract

The rotary drive system (1) using an electric motor (2) has a reduction gear turning a first drive spindle (4) with a fine thread (8). This engages in a threaded bore (11) in a nut (6) moving in a C- section guide rail (7). A second spindle (5) with a very coarse thread (9) engages in the nut and is turned as the nut moves longitudinally. The rotational speed of the second spindle is very much lower than that of the first. The second spindle is connected to an output shaft (13), and is held in bearings (12).
